Tips and suggestions

For a stronger flavor, add a few drops of instant coffee to the mix.

Make sure the jars are heat-resistant so they don’t crack during cooking.

These cupcakes are great to prepare ahead of time and take along for trips, picnics, or work.

For an extra touch, drizzle some melted chocolate on top before serving.
